RICHARD A. STRATTON, OF PHILADELPHIA, PENNSYLVANIA.

MANG-LE.

Specification of Letters Patent No. 16,887, dated March 24, 1857.

To all whom t may concern.

Be it known that I, RICHARD A. STRATTON, of the city of Philadelphia andState of Pennsylvania., have invented a. new and Improved Mangle; and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanying drawingand to the letters of reference marked thereon.

My invention consists in arranging four rollers for mangling cloths inthe following manner: Two of the rollers are placed with their centersin a line horizontally with each other, their surfaces being somedistances apart, and are caused to turn in the same direction onournals, `in suit-able frames, by gearing. Above and between these twoiirst rollers, I introduce a third roller, around which the goods to bemangled are wound. This third roller is independent of the frames andhas a rotary motion imparted to it by the contact of its surface, orrat-her that of the goods wound around it, with the two first rollers.Directly above this third roller is a fourth, which has its bearings onthe end of vertical rods, connected to levers in such a manner that thesaid roller may be elevated at pleasure a considerable distance abovethe third roller, allowing the operator to remove and replace the latterat pleasure, t-he object of the whole arrangement being in order thatthe third roller, around which the clothes are wrapped, may becomepartially wedged between the surface of the two rst rollers by thesuperincumbent weight of the fourth roller and its appendages, therebyeiliciently mangling the clothes on the third roller, without windingand unwinding them, as in ordinary mangles, the above duty beingperformed by much less exertion for the operator, while the wholemachine occupies much less space and is much less costly than the commonmangles.

In order to enable others skilled in the art to make and use myinvention I will now proceed to describe its construction and operation.

On reference to the drawing Figure 1 is a side elevation'of the machine.Fig. 2 is a detached sectional view of the rollers. Fig. 3 is a frontView of the machine.

A A are the frames of the machine in which the axles ZJ of the rollers Band B have their bearings. To these axles, and on the outside of theframe, are secured the toothed wheels C and C', into both of which vgears the pinion Gr. The latter is allowed to turn loose on a pin itsecured to the frame, and is furnished with a handle L, on turning whicht-he rollers B and B are caused to turn in the same direction. The aXlesCZ of the upper roller D are allowed to move freely in the slot at t-heupper portion of the frames A, and connected to the axles on each sideof the roller D and inside the frames are the rods E, the lower ends ofwhich are jointed to the pins z' on the bent levers F. The latter havetheir fulcrums on pins H secured to the inside of each frame, the otherends being connected together by the cross-bar f. The frames areconnected together by the stays j j and e.

K is the middle roller around which the goods to be mangled are wound.

As themachine is shown in the accompanying drawing, the roller K withthe surrounding goods to be mangled is introduced to its proper positionin regard to the rollers, readyto be operated upon. It will be observedthat the rollers B and B are a considerable distance apart, allo-wingthe roller K to be partially wedged between their surfaces by the upperroller D, which is acted upon through the rods E by the levers F. Theoperator may place his foot or hang any additional weight on thecrossbar f and proceed to set t-he rollers B and B in operation byturning the handle L. The action of the rollers (as I have found byexperiments on a large scale) have now `a tendency by their peculiararrangement not only to press the goods against the roller K but alsowind them tight aro-und the same, effectually removing all the creases.By the peculiar posit-ion of the pin 2' in regard to the fulcrum H whenthe levers F are down the weight of the latter and the cross bar f mustof themselves exert considerable force in pressing down the roller D.From this fact, together with the natural tendency of the roller Ktowedge itself bet-Ween the rollers B and B', it is evident that butlittle additional weight will be required on the ends of the levers F.The goods on the roller K being sufficiently mangled the levers F areraised by the operator to t-he position shown in red lines, whichthrough the rods E raise the roller D until its axles d rests on thetermination of the horizontal slots a in the frames A. The roller K withits goods may now be easily removed and replaced by I ain aware thatrollers have been used for mangling clot-hes, but heretofore the goodshave generally been Wound from one roller t-o another and pressedbetween their surfaces after the manner of ordinary calenders. ThereforeI do not claim clothes, but

What I do claim and desire to secure by Letters Patent is- The rollers Band B in combination With the movable roller D, arranged and drivensubstantially in the manner set forth, for the purpose of'actingupon theroller K n such a manner that the cloth on the saine may be efficientlymangled Without Winding it from one roller to another, and for thepurpose of removing and replacing the said roller K with facility.
